What is an anatomy?

(Overview of Anatomy and Physiology)

Study of Structure

2

What are subdivisions of an Anatomy?

(Overview of Anatomy and Physiology)

1. Gross or Macroscopic
2. Microscopic
3. Developmental

3

Please give samples of gross or macroscopic in anatomy?
(Overview of Anatomy and Physiology)

regional, systemic, and surface anatomy

4

Please give samples of Microscopic in Anatomy?

(Overview of Anatomy and Physiology)

Cytology and Histology

5

Please give samples of developmental in Anatomy?

(Overview of Anatomy and Physiology)

Embryology

6

What do you study about the Anatomy?

(Overview of Anatomy and Physiology)

- Mastery of Anatomical terminology
- Observation

7

What is Physiology?

(Overview of Anatomy and Physiology)

Study of the function of the body

8

What are subdivisions based on organ systems?

(Overview of Anatomy and Physiology)

Samples, Renal or Cardiovascular physiology.

9

What is the Physiology focuses on ?

(Overview of Anatomy and Physiology)

Often focuses on Cellular and Molecular level, e.g. Body's abilities depend on chemical reactions in individual cells.

10

Are anatomy and physiology Inseparable?

(Principle of Complementarity)

No, they are not separable, we have to study them together.

11

Why anatomy (structure) and Physiology (function) are inseparable?
(Principle of Complementarity)

Function (physiology) always reflects Structure(Anatomy)

12

Please levels of Structural Organization from Smallest to biggest
(Organelles is a part of the chemical level which is the smallest level of structural organization)

1.Chemical(Atoms and Molecules and organelles ----->2. Cellular (cells)-->3. Tissue (group of similar cells)--> 4.Organ (contains 2or more types of tissues i.e. heart, stomach)-->5.Organ system (organs that work closely together i.e. digestive system)-->6. Organismal (the whole body)

13

Again please levels of Structural Organization from Smallest to Biggest

Chemical-->Cellular-->Tissue-->Organ--> Organ System/System Level-->Organismal

14

Again please levels of Structural Organization from Smallest to Biggest

Atom C,H,o -->DNA-->Smooth muscle tissue--> Epithelial tissue stomach (that contain with 3 layers)-->Digestive system-->Whole body

15

Now please levels of the structural organization from Biggest to smallest

Oraganismal-->Organ system/system level--> organ
-->Tissue--> Cell-->Chemical

16

What is Humans?

(Interdependence of body cells)

Humans are multicellular, it is about 100 billion cells which are active cells.

17

What about the humans are Multicellular?

(Interdependence of body cells)

1. To function, must keep individual cells alive.
2. All cells depend on Organ system to meet their survival needs.

18

What is about Homeostasis?

(Homeostasis)

It maintain optimal, condition, in your body/ temperature and PH

19

Continue -- what is about Homeostasis?

(Homeostasis)

All body functions spread among the different organ system (level).

20

Continue -- What is about Homeostasis?

(Homeostasis)

Organ systems cooperate to maintain life.

21

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

1. Maintenance of relatively stable internal conditions despite continuous changes in environment.

22

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

2. A dynamic (ever changing/always changing) state of equilibrium (balance).

23

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

3.Homeostasis maintained by contributions of all organ systems.

24

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

4.Each body structure, from chemical to systemic level (digestive system) contributes to homeostasis.

25

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

5. Homeostasis is controlled through feedback system or Feedback system control over homeostasis.

26

The control of homeostasis is constantly being challenged by 3 factors of what?

1. Physical insult ( you feel it)
such as intense heat or lack of oxygen.

27

The control of homeostasis is constantly being challenged by 3 factors of what?
( Homeostasis)

2. Changes in the internal environment
Such as a drop in blood glucose due to lack of food

28

The control of homeostasis is constantly being challenged by 3 factors of what?
( Homeostasis)

3. Physiological stress
Such as demands of work or school

29

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

Disruptions are mild if balance is quickly restored

30

What is about the Homeostasis (subdivision meaning)?
(homeostasis)

Intense disruptions are often prolonged and result in disease (poisoning or severe infections)or death.

31

What is the Feedback system in the Homestasis?

(Feedback System)

A cycle of events in which the status of a body condition is monitored, reevaluated, and so on

32

What are examples of monitored variables (controlled conditions)?
(Feedback System)

- Blood pressure
- Temperature
- Blood glucose levels

33

What are 3 basis components of the Feedback system?

Receptor (skin-receiver)--> Control Center (Brain)--> Effector (Sweat)
So this cycle are never constantly

34

What are about 1. Integumentary System (hair, Skin, Nail)

(Organ system of the body)

1 Forms the external body covering and protects deeper tissues from injury.
2 Synthesizes Vitamin D, and houses cutaneous (pain, pressure, etc)
3.Receptors and sweat and oil glands.

35

What are about 2. Skeletal System? ( Bones, Joint)

(Organ system of the body)

1. Protects and support body organs
2. Provides a framework the muscles use to cause movement.
3. Blood cells are formed within bones.
4. Bones store minerals.

36

What are about 3. Muscular System (Skeletal muscles)
(Organ system of the body)
